On a rainy day, if there is an oil drop on tar road, coloured rings are seen around this drop. This is because of:
1 total internal refection of light
2 Polarisation
3 diffraction pattern
4 interference pattern produced due to thin films
Explanation:
: When a thin layer of oil floats on the water level. This phenomenon arises due to the interference of sun light reflected from the upper and lower surface of the film.

To demonstrate the phenomenon of interference, we require two sources which emit radiation of
1 nearly the same frequency
2 the same frequency
3 different wavelengths
4 the same frequency and having a definite phase relationship
Explanation:
: To demonstrate the phenomenon of interference, we require two sources which emit radiation of the same frequency and having a definite phase relationship.

When exposed to sunlight, thin films of oil on water often exhibit brilliant colours due to the phenomenon of :
1 interference
2 diffraction
3 dispersion
4 polarisation
Explanation:
: We see spectrum of colours when thin films of oil on water is exposed to sunlight due to phenomenon of interference.

In Young's double slit experiment, the source is white light. One slit is covered with red filter and the other with blue filter. There shall be:
1 alternate red and blue fringes
2 alternate dark and pink fringes
3 alternate dark and yellow fringes
4 no interference
Explanation:
: For interference light should be monochromatic. Red and blue filters produce incoherence, So, no interference.
